THERMO-ELECTRIC ELEMENT.

SPECIFICATION forming part of Letters Patent No. 472,037, dated April 5, 1892.

' ApplioationfiledI'ebruaryZZ1890. Serial No. 341,943.- (No model.)

I To all whom it may concern.-

Be it known that I; E1) WARD N. DICKERSON, of the city, county, and State of New York, have invented a new and useful Improvement in Thermo-Electric Elements, of which the fol-,

lowing isa full, true, and exact description,

. voltage can be obtained.

My invention will be readily understood from.the accompanying drawing, in which- A represents one metal, and B the other, alternately arranged in a pile. By preference these metals are fused together at a tempera ture suflieienmfo 'tnelt that one of the metals which melts at the lowest temperature. They may, however, be clamped together with less advantageous results. The metals I prefer to. use are a combination of sixtyparts of. antimony and forty parts of 'zinc for the plates A and nickel plates for the lates B, for which the alloy known as nicke ine may be sub- 30 stitnted. The element .is of course heated against the Hat face of one'of the laminae, as at C, the opposite side of the xcombined element being maintained in a cooler condition. The passage of the heat across the planes of 3 5 the lamina: seems to be the reason of the production-of the electricity.

'lVhat I'claim as my invention, and desire to secure by Letters Patent, is-

In a thcrmo-electric element, a series of 4c parallel plates of diflferent metals held firmly in contact witheach other and adapted to be heated at one end,-substantially as described.

In testimony whereof .I have signed my name to this specification in the presence of 45 two subscribing witnesses.
